Pipeline equipment

This machine has been designed for lining up pipes before welding.

The pipe is fastened and then lifted by means of four hydraulic arms driven by an engine with hydraulic pump and controlled via a simple radio control; another major feature of this machine is its ability to rotate the pipe in clockwise or anticlockwise direction to position the weld lengthwise as required. The rotation of the bar along its axis is achieved by a set of powered polyurethane-coated rollers, also radio-controlled, designed to rotate the pipe - including bends – and then hold it in the desired position. In addition to reducing lifting and lining-up times, this machine will operate without the need for two workers to position and fasten the choker belt, thus increasing workplace safety.

This skid is designed for use on steep slopes where pipe-laying tractors cannot work and when the cost of installation of a cableway is not justified. The skid runs on solid rubber wheels and has been built to run inside the trench, supported and driven by a winch located ahead of it.

The pipe is placed on the two rubber coated saddles and fastened to them with straps, then the sled is lowered along the slope inside the trench. When it arrives in position, a generator starts the motor on the skid and with its hydraulic system the pipe can be raised or lowered crosswise to align the pipe for clamping.

Hydraulic internal clamp for large diameter pipes (the photo shows the 100" type)

This internal clamp for large diameter pipes (from 80” up) is equipped with 3 hydraulic cylinder crowns that expand one by one at the same time with synchronized stroke of the separate cylinders. An electric motor drives the hydraulic pumps. Four rubberized motor-driven wheels drive it inside the pipe and for safety reasons the personnel assigned to the works can pass through its chassis. It is also equipped with a hydraulic winch so as to work and move safely even on an incline.
